The HardyTest UCI 3000® works on the principle of "Ultrasonic Contact Impedance ": The piezoelectric crystal causes the rod in the probe to vibrate longitudinally. The Vickers diamond at the lower end of the rod is pressed by a spring into the workpiece surface. Depending on probe choice, this is done with the thrust of 10, 50 or 100 Newton.

The rod oscillates at natural resonance frequency, which is however reduced when the diamond penetrates into the measurement object. The change in the resonance frequency also depends on the elastic modulus of the material. For this reason, the device must be calibrated in accordance with new material changes.
The frequency shift is proportional from the root of the impression surface. The device measures the change in frequency and calculates the hardness value considering the thrust and the calibration.
